Application filed pctoher 20, 1916. Serial Z L\T o. 126,717.

To all whom it may concern:

doors, having means for indicating to a chamber-maid or other person on the outside of the door whether or not the room The invention wherein the indicator is carried by the jamb of the door, and wherein such indlcator can be read by feeling or touch, so that it is as useful at night as in the day time.

One of the primary objects of the invention is to provide an indicator of the above described nature in connection with a lock of the so-called one-bolt type, that is to say, a lock having a single dead bolt which may be protracted from either side of the door. I h

Another object of the invention is .to provide a lock structure having a special indicator bolt adapted to coiiperate With an indicating devieeqon thedoorjamb, which indicator bolt is projected .concurrently with the main locking bolt when the latter is actuated from one side of the door, whereas said indicator bolt is not actuated when the locking bolt is projected from the opposite side of the door. Thus, when the door is locked from one side, the indicator on the jainb, is actuatedin a certain way, but it is not so actuated when the door is locked tron; the opposite side. Hence, it is prssil'ile to obtain an indication as to the side of the door from which the bolt has been projected, and as to the occupancy or non-occupancy of the room.

Another object of the invention is to provide a lock in which two bolts are projected a concurrently from one side, of the door,

whereas only one bolt is projected by the change key from the opposite slde of the door;

To these and other ends, the invention consists in the novel features and. combinations of parts to be hereinafter described and claimed. e

In the drawings, .F1gure l is a front elevation of door and door'fra ne equipped with a lock embodying my inv nti n; h wing t d o l k rom, th insid i Fig, is a horizontal section through eert i in t Shown in 5 Fig. is a similar View, showing the position of the parts when the door is Locked from the outside by thechange key; 4: is a ac view of the str k an the indicator associated therewith;

ig 6 is a sim ar View, sh w ng t position of the parts when the locking bolt is projected from the outside of the door by the hange'k y;

ig. 7 is an elevation of the entire lock, showing the position of the parts when the locking bolt is shot from the inside of the door by the thumb turn; and

Fig.8 is a longitudinal section through the cylinder loclg, with the change key inserted therein and turned to actuate the locking bolt.

In the particular form shown, the door "10 is mounted in a casing 11, having the usual door jamb l2, and said door is equipped with a mortise lock haying a case 13 and ;a latch bolt 14 adapted to be retracted by the usual knob mechanism 15.

A locking bolt 16in the case l3is adapted tobe actuated from the outside of the door by a cylinder lock 17 having a series of keys, ,and this "locking; bolt 16 may he actuated frto n the inside of the room by means of a thumb tnrn or the like (not shown). lVhen operated by a thuinb turn, the lock is equipped with a thumb turn hub 18 for actual ing the locking bolt. The latter bolt locks the door by engaging an opening in a strike 21 mortisejd in the usual way in.

the door iamb, and the latch bolt 14: is, in this particular instance, adapted to engage t e lower portion 20' of the strike opening. Mounted between the/latch boltand the looking bolt is .a special indicator bolt 22, which when projected is adapted to extend into the elongated strike opening 20 at the inter- ,rnediate part thereof, and at this intenmediate portion of the str ke open ng is located' an indicator operating le'ver23 lying back of and transversely to said opening and e, adapted to be engaged ,by the head of the bolt 22 in the manner shown in Fig. 2. 1 11 the present embodiment, the lever 23 is mounted at the back of a special angular plate 24 mortisedin the door jamb at the outside of. the door, The lever 23 ispivoted horizontally on this plate by means of a, pivot pin 25, said pivot pin located between the ends of said lever so that when the inner indicator plunger 26 mounted to slide in o the plate orimember 24. This plunger 26 "is "mounted in a suitable socket and surrounded by a spring 27 which is normally f 'eiitended so as to holdthe outer end of the plunger substantially flush with thev Outer "face of the plate or mounting 24:, as shown in Fig. Vllhen, however, the indicator bolt-22 is projected, as shown in Fig; 2,

v the lever 23 causes the plunger to be thrust outwardin opposition to the spring 27, and

"in this manner the end of the plunger is caused to protrude from the plate 24:, as

shown in Fig. 2, thus providing an indicator which 1s adapted to be felt by the hand from v the outside of the door. 'lVhen-the 'indi-s 1 ed position.

one position, she will know that the indica- ,tor bolt "has been thrown from the inside, andif it stands in another position she will I know that the indicator bolt has not been; projected. The arrangement of the lock parts iss'u'ch that when the locking bolt is projected from one side of the doorgithe in- I dic'atorbolt is actuated, whereas when the locking bolt is projected from the opposite side of the door the indicator bolt remains stationary in its. retracted position; and

therefore the position of the plunger 26 ca'tor is set in the position shown in Fig-.2,

the chambermaid can'readily determine by running her hand down the jamb of the door whether or not the plunger is in theextend- Then the plunger stands in indicates"whetheror not the rooinis occup1ed.

In the present embodiment, the lock parts are so arranged that both the locking bolt and the indicator bolt a're projected from theinside of the room by actuation of the thumb turn hub 18, and when the indicator bolt is projected the indicator plunger'26 is projected out of the door jamb in a line substantially parallel to the outer face of the door, so that it can be readily felt by the chambermaid. When, however, the locking bolt '16 is projected from the outside of the doorby the change key, the indicator bolt22 remains stationary in itsretracted 'position, and therefore the manual test indicator 26 is not actuated, but, on the other hand, remains with its outer end or face substantially fiushwith the surface of the door jamb, so as" not to present any pro- 'jection on the j amb. Thus, when the jamb is smooth and devoid of any projection, the

, chambermaid knows that the door has been locked from the outside, and that the room of the guest is unoccupied The means for actu atlng' the locking bolt and the indicator bolt in'the manner above described may be substantially as follows:

Thelockingbolt 16 has a shank of usual form suitably guided on the back of the 1 case. This shank is provided with a pairof talons 28 adapted to be engaged by a cam arm or rollback'29 on thecylinder lock 17 previously mentioned, when the cylinder lock is actuated by the change key 29 (Fig.

8) from the outside of thedoor. A primary tumbler 30 is bodily carried by the bolt 16, being pivoted thereto at 31. This tumbler has a lug 32 adapted to coiiperate in the usual manner with the fence or stump on the case so ashto lock the bolt either in the projected or the retracted position.

At the rear extremity of the tumbler 30,

the same is provided with a loop 34 which embraces and clears the thumb turn hub 18 with its wings 18; and on the upper Jart of the loop 3 L is a projection 35 which lies between the talons 28' and is adapted to'be engaged by the rollback in the usual manner. I i

The indicator bolt 22, which is mounted below the deadbolt, has a fiat shank suitably guided' for reciprocation in a line parallel to the locking bolt, and is adapted, under some circumstances, to 'protract the locking bolt by means of the thumb turn hub 18.

The shank 36 of the indicator bolt carries near the head of said indicator bolt an upwardly projecting shoulder 37, which eugages a'recess in theshank of the locking shown in Fi 5 this shoulder 37 en a es the forward edge of the recess in the looking bolt so that thelatter may be protracted by the forward movement of the indicator i ,bolt. carries a, 1311138 onwhlch is mounted a The shank 37 vof ,the indicator bolt secondary tumbler 39. The secondary tum- The; tumbler 39 cooperates with a fence ll ,(see Fig. 7)' cast on the back of thelock case, which is adapted to hold" said tumbler and thereby the connected indicator bolt, either in the retracted position shown in Fig. '5, or the protracted position shown in 'FigJTQ A lug 42 on the intermediate por-.

tion of the secondary tumbler is-Qlocated bolt. When the parts occupy the position above ahook. 43 depending fromthe primary tumbler 30, the arrangement being such that the depression of the secondary tumbler-by the thumb turnhub will cause a correspondmg depression oftheiprimary tumbler, so as to disengage the latter from the fence or stump 33.

When the guest wishes to lock his room against intrusion, he turns'the thumbturn hub 18 by means of the thumb turn, and

this depresses the secondary tumbler (re leasing it fronrthefence l1), Whiclrtumbler in turn depresses the prunary tumbler through the-connection 4L8, l2, and then when theprimary tumbler hasbeen pulled'out of engagement with the fence 33, the continued rotation of the hub will push the secondary tumbler for ard, carryingwith it theindicator bolt 22. The shoulder 37 on theindicator bolt engages the lO'W'Bl130T- -tion of thewsliank of the locking bolt and .tli-ereby the locking bolt is protracted concurrently withthe indicator bolt. The head of the indicator bolt may be of cylindrical form, as showmand it need, not be of any great area to actuate the 1ndicator plunger properly in the manner li'ereinbefore de scribed. As the thumb turn is turned in the opposite direction, the, bolts 22, 1 6 are released, and the locking bolt is pulled'back with the indicator bolt by means ofthe abutmentof hook 143 against the lug 4:2. When the rollback 29 of the cylinder look 17 is actuated the change lrey 29 from the "outside oz the room, the indicator bolt is a not actuated because the rollback depresses the primary tumbler individually, thereby carrying the hook .43 out of cooperation with the lug 4:2, andthe looking 'bolrt'is projected by the rollback independently,as shown in Fig. 6.

Various changes may be made'in the details of the construction without departing itheoutside knob is prevented wleien'zthedoor is bolted from tli'einsid e, but whenthe door bolted from the outside by the change key, the knob remains free because the indicator bolt :is not protracted, and does not thereffiore move the dog 1% to its operative position.

l/Vhen I refer to the indicator mechanism being inoperative when the locking bolt is protracted from one side of the door, 6. 9,,

i the outside, 1 mean that it is inoperative by the change key or other equivalent means usually employed for protracting the bolt,

as distinguished from a special shut out key. Sucha shut out key may, and usually does, actuate the indicator inthe same way as the latter is actuated by the thumb turn incohanism, but the shut outkey is used so seldom that it does not detract appreciably from the value of the indication given by the indicator mechanism.
